CFD approach for the induced effects of free wake past rivulets on cables of stayed bridges
Large-amplitude oscillations of stayed bridge cables appear under the combined effects of crosswind and rain. "Wave-like" oscillations along the whole cable length are born with large amplitudes even under low-speed wind and only the presence of the rain rivulet motion on the cable cross-section which guarantees an "all-or-none" amplification of the dynamic response of the cable. Even though this peculiar behavior has been studied, in a recent past, through dynamic and structural approaches, the phenomenon is not yet quite well understood, i.e., the quasi-cyclic oscillations seem to be activated to events (rain rivulets motion along the cables) compromising the circumferential geometry shap…
Adjuvant intravesical therapy in intermediate risk non-muscle invasive bladder cancer (NMIBC) recurring after first cycle of intravesical treatment.
Introduction and objectives The therapeutic management of intermediate risk NMI-BC recurring after intravesical therapy (IT) is not established. Cystectomy will be offered to patients at higher risk of progression but the majority will be retreated by IT. Although some Authors suggest BCG when intravesical chemotherapy (ICH) fails, some patients are retreated by ICH and some others repeat BCG adopted as first-line treatment. Not many studies have been published on this issue. The response to retreatment by intravesical therapy in terms of recurrence-free rate (RFR) and recurrence-free survival (RFS) is analyzed in 179 intermediate-risk patients. Materials and methods Only intermediate-risk …
